引言非金属燃料和含金属燃料均可用于固体燃料冲压发动机(SFRJ)。人们已研制出具有高的燃烧效率的高能含金属燃料,因为密度较高,从而可增加燃料装填量。很多燃烧研究一直使用了非金属燃料。最近,含金属燃料也很受重视。通常,含金属燃料(硼、镁、铝等等)的燃烧效率并不高,有时要用一些添加剂来提高它的性能。为了能适应实战要求,必须论证固体燃料冲压发动机在超过预定的工作温度范围时的燃料性能稳定性和燃烧特性。
Introduction Both non-metallic and metalliferous fuels can be used in solid fuel ramjet engines (SFRJs). High-energy, metal-rich fuels have been developed with high combustion efficiency because of their higher density, which can increase the fuel loading. Many combustion studies have been using non-metallic fuels. Recently, metal-rich fuels have also received great attention. In general, the combustion efficiency of metal-containing fuels (boron, magnesium, aluminum, etc.) is not high, and some additives are sometimes used to improve their performance. In order to meet the actual requirements, it is necessary to demonstrate the stability and combustion characteristics of the fuel when the solid fuel ramjet engine exceeds the predetermined operating temperature range.
